Give some time to treat regular pending messages in a function...

I have a simple linear interpolation function :

     i=1;
     while (rows[i].values[COL_DRIFT].number == 0) i++;               // Find first non-zero drift;
     j=i+1;                                                                      // Restriction : what if the second drift is genuinly 0 ???
     while (rows[j].values[COL_DRIFT].number == 0) j++;               // Find second non-zero drift;
     int iHz = j-i;                                                            // Compute the inverse number of Hz Drift is recorded at
     while (i+iHz <= csv_count)
     {
          for (j=1; j<iHz; j++){
               rows[i+j].values[COL_DRIFT].number     = (rows[i].values[COL_DRIFT].number)*(iHz-j)/iHz + (rows[i+iHz].values[COL_DRIFT].number)*j/iHz;
          }
          i = i + 4;
     }
     for (j=1; j<csv_count-i ; j++)
          rows[i+j].values[COL_DRIFT].number     = rows[i].values[COL_DRIFT].number;


However this is taking a little bit of time during which my CPropertyPageEx is not refreshed.
How do I include some call to a "refresh window" function, like say, I want to have a progress bar updated... ?

You can use UpdateWindow or RedrawWindow functions inside somewhere in your for() loops.

should've tried before asking...
I don't need to do anything, it does refresh the control auto...
Sorry to bother.

You need a function to process pending messages in the queue.  You call it during the processing in one of your loops.

eg.
void DoEvents()
{
    MSG msg;
    while ( PeekMessage( &msg, 0, 0, PM_REMOVE))
               DispatchMessage( &msg);
}
